particles. During the formation of meso-HA the surfactants could assemble together with inorganic phases, forming an inorganic-organic network as nucleation center, and subsequently produce regular pore structure when they are removed [15]. A series of surfactants, including pluronic P123 [21], sodium dodecyl sulfate (SDS) [22], and cetyltrimethy-lammonium bromide (CTAB) [16,23], have been utilized......
their applicability through strategies for linking chemical moieties on nanotubes. Surfactants, polymers, and biopolymers are mainly used in the noncovalent dispersion process of CNTs. Surfactants can enhance...]. They found that the nanotubes were dispersed or suspended very well in solvents with certain dispersive component (δd) values. The surfactants with a lipophilic group equal to and longer than decyl......
